3 Claims. (Cl. 155182) The principal object of the instant invention inthe nature of an automobile seat, davenport is the provision of anattachment for seats in or other similar piece of furniture. In theillusthe nature of upholstered chairs, davenports, car trated instance,this seat comprises a back 8 seats and the like, which attachment isspecially and a bottom It. The attachment per se rests 5L constructed toprovide a ventilated space beupon the seat as illustrated in Figs. 1 d 5tween the back of the user and the upholstered nd comp ses a base l2Which y b ade f portion of the seat against which the user would anysuitable seat material, such as metal, plynormally rest.

In

the preferred embodiment of the invention, this bumper is a channel madeof soft rubber or similar resilient material that has a rounded outersurface which reduces the wear on seat I 0 to a minimum.

In the form of the invention illustrated in Fig. 5, this bumper 32 is inthe nature of a flap 34 that extends around the edge of base I2 andoutwardly therefrom. Flap 3% may be of fabric or some suitable materialsuch as matting that would be cooler than the normal fabric forming theupholstery of seat l0.

It is obvious from the foregoing that an at- 15 tachment embodying thisinvention may be used with any upholstered seat to an advantage. Thesize of the attachment may be altered to suit conditions and the numberof strips 24 as well as their width may be determined by the use towhich the attachment is to be put. It will also be clear to one skilledin the art that seat attachments having physical characteristics otherthan that shown in the drawing might be made without departing from thespirit of the inven- 25 tion or scope of the appended claims.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent is:

1- A seat attachment of the character de- 30 scribed comprising a rigidbase; a bracket hingedly mounted on the base along each of two oppositeedges of the base and extending laterally from one side thereof; and aplurality of flexible strips joining the brackets at their outer- 35most portions and held in spaced relation to the base thereby, saidstrips each being looped around each bracket and extended around theother side of the base and in engagement therewith,

the ends of said strips being connected together for the purposespecified, said base having an apron along one edge thereof for engagingthe horizontal surface of the seat.

2. A seat attachment of the character described comprising a rigid base;a bracket hingedly mounted on the base along each of two opposite edgesof the base and extending laterally from one side thereof; and aplurality of flexible strips joining the brackets at their outermostportions and held in spaced relation to the base thereby, each of saidstrips being provided with an opening therethrough adjacent to eachbracket, the portions of the strips at the brackets being looped aroundthe brackets and passed through said openings, said strips beingextended around the other side of the base and in engagement therewith,the ends of said strips being connected together.

3. A seat attachment of the character described comprising a rigid base;a resilient. rod on one side of the base along each of two oppositeedges respectively thereof, said rod having a major portion of itslength spaced from the face of said base; a substantially U-shapedbracket having eyes formed on the ends thereof to receive the said rod,carried by each rod respectively; a plurality of flexible strips joiningthe bights of said U-shaped brackets and extending across and engagingthe other side of said base, said strips having their ends connectedtogether; and means at the ends of said strips for detachably holdingthe same together, each strip being looped around one of the said bightsof the U-shaped brackets to preclude accidental swinging thereof aboutthe rods supporting the brackets.
